Hi everyone! So my mom and I were at PETCO on Sunday because I needed some supplies and their betta section was just breaking our hearts. Not only are they selling half dead baby bettas now (ugh) but they also had one dead fish and several who weren't looking too good. We thought one of the others was dead too but then I moved it's cup and saw he was alive! Now I know the argument, if you save one it just helps them buy more, I know...but we just could not leave him. He was laying on his side, and from what I've read I'm pretty certain he does not have dropsy. I think it's swim bladder disease he seems a little bloated but not a lot and the bloat could just be an optical illusion from the way he's floating. When we got him he was just on his side he would swim a bit when the water was disturbed but that's it. We fed him part of a pea last night and he was a very enthusiastic eater and even fought to get the sinking pieces off of the bottom even though he couldn't swim all the way down because of his issue. Now I'm back at school and instructing my mom from afar; she's a newbie but does everything I tell her to; loves animals and really wants him to make it. Any advice you can give would be great! We are waiting to see if the pea will work, if there's no improvement in a couple of days should we try an epsom salt bath?
would need to see a pic for myself to try to help more but sounds like you are doing your best, could you let us know how you are keeping him at the mo, size of tank, water changes, heater, filter temp etc? continuing with the peas is a good thing if you suspect constipation, upping the water temp may also be good as it quickens their metabolism but that really depends on what temp you have him in now. I've bought bettas that were so miserable in their unheated, unfiltered dirty containers in shops before and once at home it's amazing how much they improve just from a little heat and fresh water, they actually swim rather than lie on the bottom
a filter is not so important providing your mum can keep up with the water changes but in a one gallon bowl even daily changes will not keep up with the ammonia the fish is producing. I understand that you did not expect him to survive as he is so poorly but by not providing him with the proper care to try to make him better now will never save him
